One preset

[StudioMusic]

Almost got it just the way I wanted. Spent to much time on it, but got it close enough for my pleasure. SM

You're using a variable called mult that you never define.

All your per_pixel code does is take a VERY round-about way of setting dx/dy to zero.

Although it's still kinda cool looking.

I just realized I left out the preset rating, for those that don't disable it in MD you will need to add it. Sorry, SM

[Krash]

From what I can see of that preset, what you've done is taken some dynamic swirls code, and chopped off all the important parts.
None of your per_pixel code actually does anything. Variables are defined, but never used in anything that's visible. And like Unchained said, you're basically setting dx and dy to 0.
Because all your per_pixel stuff is irrelevant, that also means that the per_frame lines defining q1-q4 are also unnecessary, and just eating up cpu cycles.

Before anyone yells at me - I haven't actually looked at this preset yet. But from the code, I can see there's a whole bunch of unnecessary calculations going on.

It's actually kinda neat. I considered trying to tame it a bit.

Hey, go easy, Krash, old boy

My ones aren't always perfect either, I just throw in some kind of geometry that I can remember and hope it looks cool.... I keep repeating unnecessary stuff too and declaring unnecessary variables.

I think it has potential, just needs to be a bit more reactive to the music, it seems to be fairly constant.... but keep going, practice makes perfect (and believe me, I'll need a lot of it!)

[StudioMusic]

I agree practice is what I need, not much time for me to make presets. My math is very rusty sinse I took college many years ago and did not have much anyway. Krash is right it has a low fps, one of my lowest. Unchained can probably make it better, but I still like it. SM

[Krash]

Not meaning to say it was bad or anything - as I said, I haven't looked at the preset (still haven't gotten around to it). I was just making observations - sorry if I got confrontational. No offense intended.

[unchained]

dunno about better, but I fooled around with it for quite a while, just 'cause.

Whole new preset if you ask me, but quite nice. SM
